Abstract

original image

{110}-faceted alloy nanocrystals: Rhombic dodecahedral Au–Pd alloy nanocrystals (NCs) enclosed exclusively by 12 {110} facets were prepared by a simple one-pot aqueous synthetic method. The picture shows an SEM image of the NCs (inset: ideal RD structure). The NCs exhibit higher surface-enhanced Raman scattering and electrocatalytic activities than {111}-faceted nanoparticles.
